Higher D‐dimer and activated partial thromboplastin time are poor prognostic factors in patients with peritoneal dialysis‐related peritonitis

Abstract

AbstractIntroductionCoagulation system dysfunction is associated with adverse outcomes of peritoneal dialysis (PD) and bacterial infection. We investigated the association between coagulation system and treatment failure of peritoneal dialysis‐related peritonitis (PDRP).MethodsWe collected records of patients aged ≥18 years with PDRP. PDRP episodes were divided into: shortened activated partial thromboplastin time (APTT) group and prolonged APTT group, low D‐dimer (DD) group and high DD group. The baseline characteristics of the groups were collected and compared. The association between APTT, DD and treatment failure of PDRP was analyzed using logistic regression analysis.ResultsThirty episodes of treatment failure were observed in 110 episodes of PDRP in our study. After adjusting for variables, prolonged APTT (OR = 1.166 [1.049–1.296], p = 0.004) or high level of DD (OR = 1.374 [1.057–1.787], p = 0.017) was associated with treatment failure of PDRP.ConclusionProlonged baseline APTT or high level of DD increased the risk of treatment failure of PDRP.
